Subject Installation: ClassNotFoundException: org.apache.openejb.loader.OpenEJBListener
Date Fri, 01 Feb 2008 06:34:39 GMT

Hi folks,

i'm new on Tomcat and OpenEJB. I had installed Tomcat 6.0.14 with some
problems, but nevertheless functioning at last. Now, i wanted to add
OpenEJB. After starting the installation procedure by copying the "war" to
webapps, when i tried to restart the server, it wasn't starting anymore. In
"stderr_...log" are "ClassNotFoundException:
org.apache.openejb.loader.OpenEJBListener" to be found.

Has anybody an idea, what's going wrong?

So far i had only followed the really simple copy operation, and i have one
speciality that possibly has something to do with that behavior.

After the installation of the "war" by tomcat, the batch file for starting
the server as a user application from the command line was changed. That
contradicts the fact, that tomcat has to be running as a service on my
system. To react on that, i executed the two lines in question by hand,

I executed by copying by hand:

copy /Y "%CATALINA_BASE%\webapps\openejb\tomcat\annotations-api.jar"

I executed by adding the environment variable to the tomcat user profile:


(In both cases the environment variables expanded...)

Is that in any matter incompatible with the way of deployment for servers in
Or will there be some other thing wrong with that EJB?

Is there any way to keep the server running, when only a subordered module
doesn't start correctly? Or do i have to keep the OpenEJB-Package deleted
until this matter is solved?
